Immigration is transforming America in a way that it had not for a century. The Immigration Restriction Act of 1921 put a ceiling on the overall number of immigrants allowed entry into the United States. The even tougher Immigration Act of 1924 followed, further diminishing the number of “undesirable” immigrants from Eastern and Southern Europe. By that time, immigration from China and Japan had also been severely limited by laws passed in 1882 and 1907. The passage of the Hart-Celler Act in 1965, however, marked a momentous reversal of these policies by re-opening immigration to a broader number of countries. Since then, immigration to the United States from around the globe has surged. Today, one-quarter of the U.S. population consists of either immigrants or children of immigrants, and they are remaking the country. Such is the story told in One Quarter of the Nation.Drawing data from various census surveys and a synthesis of historical and social-science research on immigration, Foner’s central thesis is that “post-1965 immigration has been a prominent source of profound and far-reaching changes in this country’s institutions, altering the social, economic, cultural, and political landscape in many significant ways” (4). Hence, the book is divided into chapters on race, changing cities and communities, the economy, culture, and electoral politics.The first chapter describes the effect of immigration on the racial order. In 1960, 85 percent of Americans were white; by 2018, the share had shrunk to 60 percent. Foner charts the rapid rise of the Asian and Hispanic populations and their well-being today. Increasing diversity has also raised awareness of racial identity among whites, as reflected in the current discourse on “whiteness.” Foner notes the challenges in predicting the future of the racial order, especially with growing levels of intermarriage among all groups. One plausible outcome, in line with Alba’s argument, is the eventual decline in the importance of race.1 Another possible prospect is that blacks will face greater exclusion than people of other racial groups, reflecting the legacy of slavery and generations of oppression. In any case, Foner persuasively argues that immigration has irrevocably changed the racial order and the overwhelming demographic and social dominance of the white population.The following chapters are also insightful and informative. The chapter about changing cities and communities highlights how immigrants have revitalized many places threatened with economic and demographic decline. Immigrants have deeply impacted the economy as key players in big tech as well as in the service industry at every level. Immigrants are making important contributions to popular culture, including theater, dance, food, film, and music.The chapter about electoral politics is the least persuasive. A central argument is that the presidency of Donald Trump made anti-immigrant policies a central feature of Republican Party support and induced less-educated whites and those biased against racial and ethnic minorities to move from the Democratic to the Republican Party. As a result, minority voters have become a more critical part of the Democratic Party electorate. There is some truth to this, as less-educated whites have shifted to the Republican party, and the growing number of minority voters overall provides key support for Democrats. Foner, however, could have done more to differentiate between opposition to all immigration and illegal immigration, a key distinction made by many voters. In addition, working-class voters of all races are, at least to some degree, changing their party alliances from the Democratic to Republican party. As Teixeira argued, “[S]ince 2012, nonwhite working class voters have shifted away from the Democrats by 18 margin points, with a particularly sharp shift in the last election and particularly among Hispanics.”2 This observation suggests that electoral realignments are being driven by more than just anti-immigrant and anti-minority animus, a point that Foner acknowledges but underplays.Any quibbles with the electoral-politics chapter aside, one of the book’s strengths is its strong command of history. Many contemporary public commentators on immigration are unaware that the issues and challenges that the United States faces today are similar to those of the past. For instance, worries about how immigration will change the character of communities or the racial and ethnic composition of the country have been evident since the country’s founding. Yet, Foner points out the ways in which the current context also differs from that of the past, such as the growing multiculturalism and support for bilingual education, which were not widespread a century ago.Overall, this well-written and highly accessible book is a valuable contribution to the scholarship on immigration. Its deep historical standpoint and its impressive synthesis of research on current patterns and trends provides an insightful analysis of how immigration is transforming America.
